So after talking to a shop buddy of mine, I think he may have answered my question.

"In 2012 LF changed everything to m6 hardware. It's a different size bolt with a different thread... ...You need to just use the older hardware. It's called 1/4:20 (one quarter twenty). I believe those numbers are the size of it. You can get them at Home Depot/Lowes/etc. Just make sure the 1/4:20 bolts are the right length and you're golden... ... I'm pretty sure CWB switched to m6 also for 2013. that was the only company that I never double checked though..."

Everyone switched to M6 hardware in 2013, LF did it in 2012. Also I believe in 2008(?) everyone switched from a 8" hole pattern to a 6" on their boards so if you had 2012 bindings and wanted to put them all the way out on a 2007 board you would need spacers.
